The mayor of London is being urged to make an 11th hour intervention and halt plans for a new four-lane road tunnel under the River Thames that opponents say would worsen pollution and exacerbate the climate crisis.
Tunnelling equipment is on site on the banks of the Thames, and work on the £2bn Silvertown tunnel is due to start in the coming weeks.
But the scheme has faced widespread opposition from local people, politicians, climate scientists and medical experts who say it would increase traffic and worsen public health in some of the most deprived boroughs in the country.
They also say it will lock in high carbon transport for generations to come.
